A Tick Tock Life

We're all built differently, but we're all like clocks. Each with different wiring and gears. Each ticking hand ticking down to its final second. The final second of life. We are never given a warning as to when our clocks will run out of time, hence why life is spent trying to "beat the clock". My name's Zara, and I'm a Life Horologist. Specifically, I'm a Reaper of Time. We're a very rare race, but we bear the burden of everyone's lives. Especially their time on Earth.
